La Rosa, Tucson's converted-church music venue on Country Club Road, closes out October with its annual Halloween night, Monster Mass. Doors open at 8pm for a costume-friendly night built around music and nightlife rather than family activities, continuing the venue's tradition of a themed Halloween show since opening in late 2025. It is a late-night, 21-and-up outing suited to adults looking to dress up and dance on Halloween itself rather than an earlier family-oriented event.
